    摘要： A wireless-IC-device main component is disposed on a surface opposite to a surface for receiving signals from a reader/writer. The wireless-IC-device main component includes an insulating substrate, which is provided with a loop electrode and an electromagnetically coupled module coupled to the loop electrode. A signal from the reader/writer causes an eddy current to flow across a conductor principal plane of a metal article. The eddy current causes a magnetic field to be generated in a direction perpendicular or substantially perpendicular to the conductor principal plane of the metal article. Then, the loop electrode is coupled to the magnetic field. Thus, the wireless-IC-device main component functions as an RFID tag even for signals from the principal plane opposite to the wireless-IC-device main component. Thus, it is possible to reduce the cost of manufacturing a metal article, and to provide a wireless IC device using the metal article as a radiator.

    摘要翻译： 无线IC器件主要部件设置在与用于从读取器/写入器接收信号的表面相对的表面上。 无线IC器件主要部件包括绝缘基板，该绝缘基板设置有环形电极和耦合到环形电极的电磁耦合模块。 来自读取器/写入器的信号使涡电流流过金属制品的导体主平面。 涡流导致在与金属制品的导体主平面垂直或基本垂直的方向上产生磁场。 然后，环形电极耦合到磁场。 因此，即使对于与无线IC器件主要部件相反的主面的信号，无线IC器件主要部件也起到RFID标签的作用。 因此，可以降低金属制品的制造成本，并且提供使用金属制品作为散热器的无线IC器件。

    摘要： A wireless IC device includes a spiral line electrode portion and a first capacitance electrode connected to the inner end of the line electrode portion, which are disposed on the top surface of a substrate. A second capacitance electrode opposing the first capacitance electrode and a cross line electrode, which connects the second capacitance electrode and a connecting portion that connects the top and bottom surfaces, are disposed on the bottom surface of the substrate. The connecting portion electrically connects the outer end of the line electrode portion and an end of the cross line electrode. A wireless IC is mounted such that terminal electrodes thereof are connected to the connecting portion and an end of a radiating electrode. A radiating/resonating electrode including the line electrode portion, the capacitance electrodes, and the cross line electrode can act both as a resonant circuit for a resonant tag and as a radiating electrode serving as an RFID tag.

    摘要： An antenna device includes a base including a planar conductor disposed thereon, and a coil antenna. The coil antenna includes a coil conductor wound around a magnetic core. The coil antenna is arranged such that a coil opening of the coil conductor is closed to an edge of the planar conductor. A current passing through the coil conductor induces a current in the planar conductor. Thus, a first magnetic flux occurs in the coil antenna, and a second magnetic flux occurs in the planar conductor. Therefore, a third magnetic flux occurs in an area of the planar conductor. Accordingly, the antenna device achieves a small footprint, a small-sized communication terminal apparatus and a desired communication distance.

    摘要： A radio frequency IC device achieves impedance matching between a radio IC chip and a radiation plate in a wide frequency band, and achieves desired radiation characteristics over a wide range of frequencies. A radio frequency IC device and a radio communication system allow both long-distance and short-distance communication and, in particular, allow short-distance communication using a small amount of energy. The radio frequency IC device includes an electromagnetic coupling module including a radio IC chip and a feed circuit board, and a radiation plate. An annular electrode is arranged to be coupled to both a feed circuit of the electromagnetic coupling module and the radiation plate. The radiation plate defines an electric-field radiation plate for long-distance communication, while the annular electrode defines a magnetic-field radiation plate for short-distance communication. The feed circuit board may be removed, so that the radio IC chip is coupled to the annular electrode directly or with an interposer disposed therebetween.
